Somaye Amraee Tabar; Ahmad Ershadi; Tahmine Robati

Volume 18, Issue 1 , March 2016, , Pages 203-218


  This study was performed to investigate the effect of Putrescine and Spermine on some physiological and biochemical characteristics and antioxidant enzymes activity of peach (Prunus persica cv. Alberta) and almond (Prunus dulcis cv. Rabi) seedlings under water deficit. The first factor was water regime ...  Read More

Evaluation of Peach, Bitter Almond, GF677 and GN15 Rootstocks for Bicarbonate or Iron Deficiency-Induced Chlorosis

Razieh Rostami; Ahmad Ershadi; Hasan Sarikhani

Volume 17, Issue 2 , June 2015, , Pages 341-355


  In order to evaluate tolerance of four Prunus rootstocks to Fe-deficiency-induced Chlorosis,  an experiment was carried out in Bu-Ali Sina University in 2012 using a RCBD design with four replications. Four rootstocks were used, including GF677, GN15, bitter almond and peach and nutritional treatments ...  Read More

Effect of soybean oil and naa on delaying bud break and reducing spring low temperature damage in grape cv. Fakhri

Shima Chayani; Ahmad Ershadi; Hasan Sarikhani

Volume 17, Issue 2 , June 2015, , Pages 357-371


  Delaying bud break, using chemicals is an approach to avoid spring frost damage. Therefore, the effect of spraying different concentrations of soybean oil and naphthalene acetic acid (NAA) on delaying bud break, altering internal atmosphere and cold hardiness in grape cultivar ‘Fakhri’ was ...  Read More

Effect of foliar application of methyl jasmonate in cold tolerance improvement of greenhouse-grown cucumber cv. ‘Negin’ seedlings

Shiva Bazl; Rouholah Karimi; Ahmad Ershadi; Alireza Shahbodaghlo; Mousa Rasouli

Volume 17, Issue 2 , June 2015, , Pages 441-455
